Answer:
The answer is 2 hope this helped!
Step-by-step explanation:
Answer:
Part A: So the solution for 4 = 2x-1 is -2. Why they're intersecting is because <em>x</em> is -0.5 in both cases. 2/4, as we already know, is 0.5. Since, this -2/4, we can just make 0.5 negative, so -0.5. -0.5 times 4 = -2, so x is -0.5. For y = 2x-1, multiply -0.5 by 2, which would get you -1. Then after that subtract 1, for -2.
Part B:
Well, notice how none of the entries for y = 4x and y = 2x-1 match. That would mean the answer wouldn't be an integer. (Attachment is the table)
Part C:
First, graph both y = 4x and y = 2x-1. After that, find where the two equations' y-coordinates are the same (So, on a graph, where they intersect.). The y-coordinate in common is your answer.
The simplified answer is 17.48
Answer:
Explanation:
You just need to find the ratio of lengths of one of the sides and apply it to the unknown side:
72

=
3
This means that the triangle on the right has sides that are 3 times the length of the smaller triangle.
